The results showed that malic enzyme exists in heart, gonads, eyes and gills tissues in both female and male V. macrolepis. There was only one ME-2 in heart and ME-1 in eye of female fish, while there were ME-1 and ME-2 in heart and ME-2 in eyes of male fish. Ovary contained ME-1 and ME-2, while spermary only contained ME-1. In kidney and spleen tissues, malic enzyme was found only in female fish, while in muscle, malic enzyme existed only in male fish. The phenotypic of malic enzyme had obvious differences no matter in the same organ of different sexes in V. macrolepis or different organs in the same sex. But there were no differences among different individuals of the same sex. The results will provide basic data for developmental genetics, breed improvement and directed breeding of V. macrolepis, and lay a foundation for its development and protection.展开更多

It had been found for the first time that the phenotype of malate dehydrogenase (MDH),acid phosphatase (ACP) and superoxide dismutase (SOD) showed difference between male and female V. macrolepis,and there was no difference among different individuals in the same sex. Therefore,the electrophoresis band of malate dehydrogenase,acid phosphatase and superoxide dismutase could be used as an indicator for the identification of gender and tissues of V. macrolepis,which would provide basic data for the developmental genetics,variety improvement and directed breeding of V. macrolepis groups,thus facilitating the development and protection of this valuable fish species.展开更多
